2-Nitrimino-5,6-dinitrobenzimidazole (1) was synthesized by nitration of 2-aminobenzimidazole at ambient temperature in good yield. In order to explore new insensitive explosives four energetic nitrogen-rich 1:1 salts such as the guanidinium (1a), aminoguanidinium (1b), triaminoguanidinium (1c) and hydroxylammonium (1d) were synthesized either by facile acid/base or in situ metathesis reaction. In addition 2-nitrobenzimidazole (2) was synthesized by the reaction of 2-aminobenzimidazole using potassium hyperoxide in THF. Different nitration methods were tested to obtain a theor. 2,4,5,6,7-pentanitrobenzimidazole but only the already known 4,5,6,7-tetranitrobenzimidazol-2-one (3) could be isolated. All synthesized compounds were characterized especially by low temperature X-ray diffraction, CHN elemental anal. and 1H and 13C NMR spectroscopy. The heat of formation of all new synthesized compounds was calculated using CBS-4M electronic enthalpies in combination with the atomization method to calculate their detonation parameters with the EXPLO 5 V5.05 computer code. The experimental process involved the reaction of 2-Nitro-1H-benzo[d]imidazole(cas: 5709-67-1).Application of 5709-67-1

And the article contained the following:

Fibroblast growth factor receptor (FGFR) is a promising therapeutic target for cancer treatment. A series of 5-aminopyrazole and 5-amino-1,2,3-triazole derivatives were designed as FGFR inhibitors based on the docking mode of Debio1347 within the FGFR kinase domain. The inhibitory effects on FGFR2 kinase and the antitumor activities against human gastric cancer SNU16 cell lines were evaluated. Furthermore, the preliminary structure-activity relationships (SAR) were discussed. The results demonstrated that several compounds presented good potency against FGFR2 kinase. 1-(5-Amino-1-(2-methyl-1H-benzo[d]imidazol-6-yl)-1H-pyrazol-4-yl)-1-(1H-thieno[3,2-b]pyrrol-2-yl) methanone (I) and 1-(5-amino-1-(2-methyl-1H-benzo[d]imidazol-6-yl)-1H-1,2,3-triazol-4-yl)-1-(1H-indol-2-yl)methanone (II) were the most potent with IC50 values of 3.3 and 2.3 nmol路L-1, resp., which were similar to that of Debio1347.

This paper introduces a simple model for prediction of one electron reduction potential [E(RNO2/R鈥O2-)] of various nitroaryl compounds The new method uses energy difference between HOMO (HOMO) and LUMO (LUMO) in gas phase at the B3LYP/6-311++G** level (螖EHOMO-LUMO) and some structural parameters. It was used for 35 nitroaryl compounds including nitrobenzenes, nitrofurans, 2-nitroimidazoles, 4-nitroimidazoles, 5-ninuintidazoles, nitroazaindoles, nitroacridines, and miscellaneous nitroaryl compounds The root mean square (rms) percent deviation and the average absolute error of predictions of E(RNO2/R鈥O2-) relative to experiment were decreased from 12.4 % and 0.42 V to 3.5 % and 0.11 V, resp., upon consideration of several structural parameters.

The heterostructured Ag nanoparticles decorated Fe3O4 Glutathione (Fe3O4-Glu-Ag) nanoparticles (NPs) were synthesized by sonicating glutathione (Glu) with magnetite and further surface immobilization of silver NPs on it. The ensuing magnetic nano catalyst is well characterized by Fourier transform IR spectroscopy (FTIR), SEM (SEM), high resolution transmission electron microscopy (HRTEM), powder X-ray diffraction (PXRD), thermogravimetric anal. (TGA). The prepared Fe3O4-Glu-Ag nanoparticles have proved to be an efficient and recyclable nanocatalyst with low catalyst loading for the reduction of nitroarenes GC6H4NO2 (G = 4-OH, 2-NH2, 4-Br, etc.), 1-nitro-naphthalene and heteronitroarenes such as 5-nitro indole, 2-nitro benzimidazole to resp. amines GC6H4NH2, 1-naphthylamine and heteroaminoarenes such as 5-amino indole, 2-amino benzimidazole in the presence of NaBH4 using water as a green solvent which could be easily separated at the end of a reaction using an external magnet and can be recycled up to 5 runs without any significant loss in catalytic activity. Gram scale study for the reduction of 4-NP has also being carried out successfully and it has been observed that this method can serve as an efficient protocol for reduction of nitroarenes on industrial level.

On November 15, 2019, Abdulazeez, Ismail; Khaled, Mazen; Al-Saadi, Abdulaziz A. published an article.Computed Properties of 5709-67-1 The title of the article was Impact of electron-withdrawing and electron-donating substituents on the corrosion inhibitive properties of benzimidazole derivatives: A quantum chemical study. And the article contained the following:

The role of substituents in the enhancement of corrosion inhibition effectiveness in some organic compounds has been the subject of several studies in recent years. Understanding the relationship between corrosion inhibition performance and electronic properties of the mol. shall facilitate the design of efficient inhibitors and reduce the burden of exptl. trials involved. In this study, quantum chem. calculations using d. functional theory (DFT) method were performed on benzimidazole and its derivatives involving various electron-withdrawing and electron-releasing substituents. Several reactivity indicators, such as frontier orbitals, energy gaps, electronegativity, electrophilicity and global hardness were calculated and correlated with available exptl. data. Frontier orbital energy gap predicted 2-nitrobenzimidazole to possess higher anti-corrosion properties, while electronegativity, electrophilicity and global hardness predicted 2-aminobenzimidazole to exhibit higher corrosion inhibition tendency. Results of mol. level interaction studies predicted that the adsorption of the mols. over the iron surface would take place preferentially through the nitrogen atoms of the imidazole ring and the carbon atoms of the benzene ring, resulting in the formation of Fe-N and Fe-C bonds with 2.00-2.40 脜 bond distances which lie within the range of the chemisorption interaction. The experimental process involved the reaction of 2-Nitro-1H-benzo[d]imidazole(cas: 5709-67-1).Computed Properties of 5709-67-1
